Suppose a piece of steel has no initial carbon but is subject to a surface concentration of 2.0 percent. The carbon at the surface will diffuse into the steel. It is desired to have a concentration of 9.400e-03 percent Carbon at a depth of 9.0 mm. If the process is to take 7.807e 07 seconds, at what temperature should the process occur (in Celsius)

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
